# **Search, Retrieval, Training, and Analytics with Modern AI Data Lake By Chang She**

As AI systems become increasingly complex and data-driven, the underlying infrastructure for search, retrieval, training, and analytics has emerged as a critical bottleneck. This talk explores the next generation of AI data lakes, presenting a comprehensive approach to managing large-scale, multimodal datasets that can dramatically accelerate machine learning workflows.

Drawing from his extensive experience in working with the most cutting edge Gen AI companies, LanceDB’s CEO Cofounder Chang She will demonstrate how modern data infrastructure transforms AI development. The presentation will cover innovative techniques for efficient vector search, optimized training pipelines with dataset construction, and integrated analytics, showcasing real-world implementations from leading AI companies that highlight the potential of purpose-built data management solutions.

## **About Chang She**

Chang She is the CEO and cofounder of LanceDB, the developer-friendly, open-source database for multi-modal AI. A serial entrepreneur, Chang has been building DS/ML tooling for nearly two decades and is one of the original contributors to the pandas library.

# **Solving Scala's Build Problem with the Mill Build Tool By Li Haoyi**

Mill is a Scala build tool that improves upon every aspect of the venerable SBT toolchain: more performant, easier to understand, and scalable to larger codebases. Unlike most build tools, Mill makes build configuration easy: easier to write, easier to navigate, and easier to understand. This talk will explore how Mill works, demonstrate its advantages over SBT in a live-coding setting, and dive into the novel techniques that a modern build tool uses to improve upon older build tools of years and decades past.

## **About Li Haoyi**

Li Haoyi graduated from MIT with a degree in Computer Science and Engineering, since then has built core infrastructure for high-growth companies like Dropbox and Databricks, and has been a major contributor to the open source community. Author of the "com-lihaoyi" suite of OSS Scala projects, these projects have over 10,000 stars on Github, and are downloaded over 20,000,000 times a month. Haoyi has deep experience in the JVM and has professionally built distributed backend systems, programming languages, high-performance web applications, and much more.
